In some cases this may damage the controller chip.
In the case of performing a short circuit tests on "LDO output" power rails it is especially important to disconnect the LDO regulator from the power rail, because the electrical current during a short circuit test will also flow into the output pin of LDO regulator which is much more sensitive to such damage than "Switch node pin".
